Interactive origami art with Raspberry Pi
Ross Symons is an incredible origami artist who harnessed Raspberry Pi and Bare Conductive’s Pi Cap board to bring his traditional paper creations to life in an interactive installation piece.
The Pi Cap is “[a]n easy-to-attach add-on board that brings capacitive sensing to your Raspberry Pi projects.” Capacitive sensing is how touchscreens on your phone and tablet work: basically, the Pi Cap lets the Raspberry Pi know when something – in this case, an origami flower – is being touched.
Ross named his creation “Wonder Wall – an Origami Meditation Mural”. Visitors put on headphones next to the origami flower wall, and listen to different soothing sounds as the Pi Cap senses that one of the green flowers is being touched.
The Raspberry Pi runs code from Python library PyGame to achieve the sound effects.
64 origami flowers were mounted to a canvas, a much lighter and more readiliy transportable option than a big wooden board.
On the back of the board, the Pi Cap and Raspberry Pi connect to each origami flower with electric paint and copper tape. The electric paint “solders” the copper tape to the Pi Cap, and also allows for connections around corners.

Check out Ross’s beautiful Instagram account @white_onrice. It’s full of incredible paper creations and inspired stop-motion animations. Our favourite is this little crane having a whale of a time.

I painted a black and white picture of a tiger with RGB LED behind the eyes. Touching different stripes changed the colours of the eyes. It used conductive paint and an Arduino Nano with the capacitive sense library. Because there does not have to be actual touch it is possible to overpaint the black conductive paint or put it behind other materials.
